The Lowdown
Alright, folks. Rusty here. Let’s get straight into it. We’ve got a solid run of surf coming up at Lakey Pipe, so no gaps to worry about right from the start.
The overall pattern is a long, consistent stretch of SW groundswell with cross-offshore winds. The water temp is about average for the time of year, nothing wild there.
Starting Wednesday the 26th, we’ve got clean 6ft surf from the SW with a period of 14 seconds. The combined swell energy is moderate (1212). It’s a little on the bigger side for beginners, but for the experienced crew, it’s excellent.
Thursday the 27th drops a touch to 4ft, still clean and glassy with light cross-off breezes. The energy eases a bit (1072), but the period stretches to 16 seconds, giving those waves real shape. Points and reefs will love this.
Now, Friday the 28th is your standout. Swell jumps to 8ft from the SW with a period of 17 seconds. The combined energy is strong (4343). That’s a powerful groundswell. The wind is a light cross-off, keeping it ultra clean. This is for experienced surfers only – it’s going to be pumping. Crowds are likely here, so be early.
Saturday the 29th holds at 7ft in the morning, still clean and with a long 16-second period. The energy is still strong (2249). It eases to 6ft by the afternoon. Another top-notch day.
Sunday the 30th and Monday the 31st see the swell back off to 5ft and 4ft, but the period on Monday hits 19 seconds – very long period groundswell. The energy is moderate (1402). That kind of long period can make beach breaks a bit straight, but at a reef like Lakey Pipe, it’s going to be lined up and offering some really long rides.
Tuesday the 1st of September through to the 3rd, the swell pulses back up to 7ft and 7ft, with long periods. The wind is still cross-off, but there are a few afternoon sessions with a slight cross-chop. Still very good, but the mornings are the pick.
Saturday the 5th of September has some light cross-shore winds and a bit of ripple, so it’s less clean than the other days. The swell is still there at 6ft to 6ft, but the quality is a notch down.
The second week has a couple of promising pulses. Sunday the 7th and Monday the 8th of September sees clean 6ft to 6ft SSW swell, with light winds and strong energy (1447). By the 9th of September, the wind picks up to a moderate breeze, but it’s offshore from the ESE, so it’ll be clean and powerful with 7ft swell. The 10th of September has a final push of 8ft SW swell, strong energy (3570), but with a moderate cross-off wind. It’s a big, powerful end to the run for experienced surfers only.
Top pick is Friday the 28th of August. 8ft SW groundswell, 17-second period, strong energy (4343), and light cross-off winds. It’s a classic.
Rusty.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
